Opera users typically were hardcore about it, and would only let go when you pried their cold dead hand away from it. I've been a longtime Opera user...the new version is derisively called "Chropera" and I've dumped it. It's just bad, so many of the things that made Opera are gone, so why use this Chropera? It didn't even have a bookmark manager, just that stupid Speed Dial. And then there is the general evasiveness of the devs, especially about a Linux version.
So if you've forgotten about it, consider it a mercy. For those of us who loved using Opera, it's very painful.
